AGRICULTURAL IMPLEMENT.

Specification of Letters Patent. Patented Aug 20, 1918 Application filed September 4. 1917. Serial No. 189,579.

To all whom it may concern:

Be it known thatI, WILLIAM PARRIOTT, a citizen of the United States, residin at Detroit, in the county of Wayne and tate of Michigan, have invented certain new and useful Improvements in Agricultural Implements, of which the following is a specification.

This invention relates to certain new and useful improvements in agricultural implements and relates more particularly to plows.

The primary object of the invention resides in the provision of a plow having adjustable connections between the handles and the frame, whereby the plow proper or cultivator blade may be raised or lowered without materially changing the incline of the handles. '7 7 Another object of the invention resides in the provision of a connection of this character and adjusting levers which may be readily incorporated in a walking cultivator or other form of agricultural implement without materially increasing the cost of the same. j

A further object resides in the provision of a plow or cultivator in which the parts may be readily adjusted to vary the depth of the furrow, as desired. 7 a

With these and other objects in view, as will be apparent from the following paragraphs, the invention resides in the novel construction, combination and arrangement of parts aswill be hereinafter more specifically set forth, pointed out in the appended claims and shown in the drawings, in which Figure 1 is a side-elevation of the complete device with the parts shown in novel position by full lines and in the other 'extreme position by dotted lines.

Fig. 2 is a to plan view, and

Fig. 3 is a rear elevation of the lower portion of the device.

Referring more particularly to the drawings, in which similar reference characters designate corresponding parts throughout the several views, the numeral 1 designates the guide wheel upon the axle of which is mounted the frame of conventional form. This frame includes a beam 2 having its forward end pivotally secured to the axle 3 of the wheel and having its rear end curved downwardly to support the cultivator blade 4 the downwardly curved portion of said beam providin a standard 5.

The upwar y diverging handles 6 are connected at their lower ends to the opposite sides of the handle carrying member 7, the upper end of which terminates below, the upper rearwardly turned extremities 8 of said handle 6 and between the latter, a connecting and bracing cross bar 9 being. extended through the upper extremity of said member 7 and secured in the sides of said handles 6, as clearly shown in Fig. 2.

The extended lower end of the member 7 is pivoted, as shown at 10, between the links 11, one of which is of substantially triangular form and has its lower corner mounted upon the pivot pin 12, extended through the curved rear end "5 of the frame 2 and also serving as a pivot for the lower end of the opposite link 11. It will be understood that the pivot pin 10 extends through the upper rear corner of the triangular link 11 while i an integral lever 13 extends upwardly from the upper forward corner of said'triangular link 11. The urpose of the lever 13 and the" triangular link Y11 and its complementary link designated by the same numeral, will presently appear.

Pivoted to the upper portion of the handle carrying member 7 are the links 14:,fone of which links is extended to form an adjusting lever 15.- The links 14 are connected by apivot member 16, upon which are mounted the upper ends of the upper adjusting bars 17 which bars are arranged in parallel rela-" tion and have their lower ends mounted upon the pin 18, which latter forms a joint upon the pin 12, within the frame 2.

It will be evident that, owing to the connection between the handles and the frame of the implement, it will simply be necessary to swing upwardly the adjusting lever 15 to break the joint between the upper and lower adjusting rods 17 and thereby force the cultivator blade or shovel 4 deeper into the ground and thereby increase the depth of the furrow, without materially changin the angle or incline of the handles 6. If, ow-.

ever, the handles6 should be carried too far forwardly, the adjustin lever 13 may be readily operated to sw ng forwardly the connection" the] latter.

lower end of the handle member 7 and thereby throw rearwardly the upper ends 8 of said handles 6. This adjustment of thecultivator blade or shovel 4 and the handles 6 may be readily accomplished.

WVh-ile thefdrm of the invention shown and described is What is believed to be the preferred embodiment thereof, it is neverthe less to be understood that minor changes may be made therein within the scope of the appended claims, Without departing from the spirit of the invention.

l ms 1. In an agricultural implement, the combination with the guide wheel and axle and blade carrying frame mounted on said axle, of a handle supporting member, link connection s between said handle supporting member and said frame, upper adjusting bars,

lower adjusting bars mounted on said axle, a lever carried by said handle supporting member, sa1d upper ad usting bars being pivotally connected with said lever, and a pivotal connection between said upperad justing bars and said lower adjusting bars.-

2. In an agricultural implement, inseambiiia-tion with a ealavatorfiame, a blade mounteduponone end of said frameQa-n axle carried by the opposite end 'of said frame and awheel' mounted upon said axle, of a handle carrying member, handles mounted upon said member, a pair of links: connecting said member withfsaid frame at its rear end, one of saidlinks being extended form lever, pivoted adjusting bars connecting the upper portion of sa dinem'ber with said axle, and a bar connecting said links with said ad usting bars at the point of 3. In an agricultural implement, the com bination with the blade carrying frame "and guide wheel axle, of a'h'andle supporting member, handles carried by said member,

links at the lower end of said member, a pivot IHGiTIbGD COHIiBCtJHg sald links with said frame, a barmounted upon sald pivot member, lower adjusting bars pivoted upon said last mentioned and niountedupon said axle, upper ad usting bars pivoted upon the first mentionedbar, a lever pivoted to said handle carryingmembjer, and pivotal connect onbetween said lever and said upper adj Listing bars.
